Investigation by Raman Spectroscopy of the Decomposition Process of HKUST-1 upon Exposure to Air

Figure 5

(a) Position (black squares) and intensity (red circles) of the Raman peak at about 502 cm⁻¹ for HKUST-1 as a function of time of exposure to air moisture. (b) Raman spectra in the region of the peak at about 502 cm⁻¹ acquired for the HKUST-1 after 3 hours, 20 days, and 165 days of exposure to air moisture.
